Abstract

Methods, systems and computer readable media for in-band management using L2 addresses over a B-VLAN in an SPBm network.

Claims (30)

1. A method comprising:

configuring, at one or more processors, a virtual local area network (VLAN) mapped to an in-band management I-component service identity (ISID);

adding, at the one or more processors, a port to the VLAN, wherein the port is coupled to a network management system;

allocating, at the one or more processors, a base VLAN media access control (MAC) address based on a chassis MAC address;

sending, from the one or more processors, a gratuitous Address Resolution Protocol (ARP) message; and

encapsulating one or more Layer 3 (L3) packets received from the management system using a MAC-in-MAC header on the in-band management ISID.

2. The method of claim 1 , wherein the encapsulating further comprises:

adding an encapsulation header having source and destination MAC addresses, a Backbone Virtual Area Network (BVLAN) and a management ISID.

3. The method of claim 1 , further comprising configuring an Internet Protocol (IP) subnet associated with the network management system.

4. The method of claim 1 , further comprising decapsulating a received packet associated with the in-band management ISID and forwarding the decapsulated packet to a processor associated with a receiving Backbone Edge Bridge (BEB).

5. The computer readable medium of claim 1 , wherein the operations further comprise decapsulating a received packet associated with the in-band management ISID and forwarding the decapsulated packet to a processor associated with a receiving Backbone Edge Bridge (BEB).

6. A system comprising one or more processors configured to perform operations including:

configuring, at one or more processors, a virtual local area network (VLAN) mapped to an in-band management I-component Service Identity (ISID);

adding, at the one or more processors, a port to the VLAN, wherein the port is coupled to a network management system;

allocating, at the one or more processors, a base VLAN media access control (MAC) address based on a chassis MAC address;

sending, from the one or more processors, a gratuitous Address Resolution Protocol (ARP) message; and

encapsulating one or more packets received from the management system using a MAC-in-MAC header on the in-band management ISID.

7. The system of claim 6 , wherein the encapsulating further comprises:

adding an encapsulation header having source and destination MAC addresses, a Backbone Virtual Area Network (BVLAN) and a management ISID.

8. The system of claim 6 , wherein the operations further comprise configuring an Internet Protocol (IP) subnet associated with the network management system.

9. The system of claim 6 , wherein the operations further comprise decapsulating a received packet associated with the in-band management ISID and forwarding the decapsulated packet to a processor associated with a receiving Backbone Edge Bridge (BEB).

10. A nontransitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to perform operations including:

configuring, at one or more processors, a virtual local area network (VLAN) mapped to an in-band management I-component Service Identity (ISID);

adding, at the one or more processors, a port to the VLAN, wherein the port is coupled to a network management system;

allocating, at the one or more processors, a base VLAN media access control (MAC) address based on a chassis MAC address;

sending, from the one or more processors, a gratuitous Address Resolution Protocol (ARP) message; and

encapsulating one or more packets received from the management system using a MAC-in-MAC header on the in-band management ISID.

11. The computer readable medium of claim 10 , wherein the encapsulating further comprises:

adding an encapsulation header having source and destination MAC addresses, a Backbone Virtual Area Network (BVLAN) and a management ISID.

12. The computer readable medium of claim 10 , wherein the operations further comprise configuring an Internet Protocol (IP) subnet associated with the network management system.
